The String Armonica: A New Class of Synthesizer

The String Armonica has been upgraded with several key improvements and new features to expand its capabilities. This version includes adjustable string height with redesigned bridges and custom-polished steel pickup plates for improved tone and performance.

Each unit comes with a custom hard shell case.

New built-in modes:

• Staccato Mode: Adjust note duration for sharper, more defined sounds.

• Harp Sweeping Function: Use the pitch wheel to sweep seamlessly across strings.

• Arpeggiator: Choose from five patterns for dynamic, rhythmic sequences.

• Envelope Mode: Notes automatically fade in with adjustable timing for smooth, expressive playing.

We currently have the first batch of seven ready for purchase. They will ship within five days of ordering.

Here is a quick preview of the new functions:

*USB TO MIDI DONGLE NOT INCLUDED

If you want to play this instrument without a computer, you will need a keyboard with 5 Pin MIDI Output. We recommend a 61 key controller like the M-Audio Keystation 61 MK3

Otherwise, you will need to use a USB to MIDI dongle along with your computer/DAW. You can also use a USB MIDI Host (not included) to play it without a computer. For an affordable option, we recommend this dongle from Amazon. Using sub par dongles can result in an inconsistent performance or sticking notes.

If you'd like to use an expression pedal, we recommend this as an affordable option:

M-Audio EX-P

Please watch the Tuning and Voicing video prior to purchasing, so that you know what to expect upon receiving your instrument.

Here is an interactive web app tuner we made to help customers easily tune their instrument: https://soundstone.co/pages/string-armonica-tuner

We also highly advise reading the manual prior to purchasing.

Overview:

The String Armonica reimagines musical synthesis by using strings, instead of electronic waveforms, as its sound source. This instrument employs 12 chromatically tuned strings, each harmonically resonating through a custom-built internal synthesizer. This setup enables users to play a range of four octaves using a MIDI keyboard, with all strings capable of sounding simultaneously in full polyphony. The strings function similarly to speakers, being precisely tuned to respond to the synthesizer's output. Imagine an array of 48 strings, each with its own Sound Stone sustainer, but all controlled through a keyboard or MIDI interface for a unique and rich musical experience.

The String Armonica also features additional expressive controls for enhanced musicality. An external expression pedal allows for nuanced dynamic control, and an onboard tremolo system can be operated through a MIDI keyboard's mod wheel. This functionality gives the player the ability to pulse the strings, adding depth and texture to the sound.

The String Armonica has a unique timbre, reminiscent of the Glass Armonica, which is how we stumbled upon the name. It can sound like a variety of instruments including a celesta, a reed organ, or singing bowls. We believe it will be a great tool for composers to add a new layer of high harmonic richness to their compositions.

It's capable of producing both infinitely sustained and staccato notes. Players can control the decay of these notes using the included felt damper. Each string is equipped with an individual pickup, which is summed to a stereo output, allowing a wide sound field and immersive experience.

NOTE:

As with any complex stringed instrument, the tuning process has a learning curve. You may find it slightly difficult to initially learn how to properly tune the instrument so that each octave is of uniform volume. Again, please watch the tuning and voicing video before purchase, so that you will know what to expect. We will assist any customers if they are having trouble.

When playing sustained chords, rather than staccato notes, we suggest using the damper. This will help equalize the pitch of the strings during the initial attack and lead to stability. In addition to this, we’ve found that using the expression pedal to swell the notes or playing with a lower MIDI volume leads to a better sound.

Please note: International orders will most likely need to pay customs and/or duties fees upon delivery. Please consult your domestic policies before placing an order.

Tuning and Maintenance:

Tuning the String Armonica is an art in itself, allowing for a personalized sound. Voicing the instrument is crucial and will be important for each user to learn. In order to achieve equal volume across all octaves, it must be tuned correctly. This is more complex than just tuning to the fundamental note of each string. Due to string tension and inharmonicity of harmonics, you will want to tune each string slightly flat, so that the higher octaves are as loud as the fundamental. The instrument will still be in concert pitch, so long as its tuned correctly. The tuning process entails a learning curve, which will become easier over time. We can help guide each user if they are having any difficulty learning.

Strings will be detuned prior to shipment and will need to be retuned and acclimated once each unit is received.

Connect and Control:

Easily connect the String Armonica to various audio setups via standalone 5 pin MIDI keyboard or a DAW on a computer. User's must have a MIDI keyboard with 5 pin MIDI output or will need to use a USB controller in conjunction with their DAW and the supplied USB to MIDI dongle that we provide.

Here are performances of the String Armonica (earlier versions) played with MIDI and a MIDI keyboard.

Returns and Warranty:

Limited One-Year Warranty: We stand behind the quality of our instruments.
60-Day Return Policy: Satisfaction guaranteed.
Users must pay for return shipping as well as insurance unless their unit has factory defects

Feedback:

Because this is a brand new instrument, we hope users will share any thoughts they have for improvement and will be patient learning how to use the instrument. Similar to an autoharp or piano, there will be a learning curve with how to properly voice the instrument so that all octaves have an even keeled volume response.

Thank you for your interest in our new instrument!
